Lempkee currently has the largest and best CD≥≤ ISOs FTP online
, but unfortunately I haven't actually experienced it myself since it is private access only.
You have to upload a CDTV/CD≥≤ game that he/she/it doesn't have. And I don't even have any Amiga CD games full stop, let alone any rare ones.
I pray that soon he will make the FTP public access, and end my misery
